China’s fast food scandal has spread to Burger King, Starbucks and the Japanese branches of McDonalds as the chains admit using rotten meat from a supplier in Shanghai.

On Tuesday, Starbucks
said some of its cafes previously sold products containing
chicken originally sourced from Shanghai supplier Husi Food Co
Ltd, Reuters reports. Starbucks says it removed from shelves
sandwiches made with chicken that originated at Husi.

McDonald’s apologized on Monday to Chinese customers for
apparently using rotten chicken and beef from Husi in its
products, and has admitted that Japan branches have also sourced
meat from the Shanghai company since 2002. The fast-food chain
said it stopped selling chicken McNuggets supplied by Husi at
more than 1,300 outlets across Japan.

Burger King and Pizza chain Papa John's have also stopped using
the Husi meat products.

Husi's food processing plant in Shanghai was closed on Sunday by
the China Food and Drug Administration after a TV expose showed
workers using expired meat and picking up meat dropped on the
floor to use as part of its products.

In China, McDonalds and Yum Brands which owns KFC and Pizza Hut
were first to be affected. Yum's KFC is China's biggest
restaurant chain, with more than 4,000 outlets and plans to open
700 more this year. Both McDonalds and Yum have 7.6 percent of
Chinese food market.

In a statement, Husi said it would cooperate with the
investigation and promised to share the results with the public,
AP reports.

"Our company management believes this to be an isolated
event, but takes full responsibility for the situation and will
take appropriate action swiftly and comprehensively," Husi
said.
